Shocked!

On the way to school Monday morning Alex was asking about people's full names.  We went through the list, but when we got to my dad an argument broke out.  He asked what PawPaw's name was.  I told him my dad's real name.  When I got finished he waited a second and started fussing, "That's not right!  You didn't say Ditney Momma.  What you said is not PawPaw's whole name!"  I still don't think he believes me that Ditney is not my dad's real name.
